AUTOMATIC ELECTRICAL BOOT-BLACKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 527,977, dated October 23, 1894. Application filed April 2, 1894. Serial No. 506L054- (No model.)

To all whom, it may concern: i

Be it known that I, JOHN O. HEINZE, J r., of Lynn, county of Essex, and Commonwealth of Massachusetts, have invented certain new and usefullmprovements in AutomaticElectrical Boot-Blaoking Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which.

it appertains to make and use the same.

My invention relates to certain new and useful improvements in electrical boot blacking machines and also to mechanism for an tomatically starting said machines, and its general object is to provide a machine of this class, simpler in construction and more convenient of operation than those heretofore novel features, arrangements and combina tions hereinafter particularly described and pointed out in the claims.

Figure 1 represents a side elevation of the machine with the side casing removed to show its construction. the machine with parts of the top casing broken away to show certain parts ofv the mechanism. Fig. 3 is a detail view ofthe automatic electric circuit closing device showing the parts in their positions when the circuit is closed. Fig. 4: is a side view in sec tion of the blacking pot. Fig. 5 is a similar View showing the piston as moved down to supply. the blacking brush with blacking. Fig. 6 is an end view of the blacking pot showing grooves out in the face of the piston to hold the blacking which is to be supplied to the brushes.

Like letters of reference refer to like parts throughout the several views.

Within the caseA of the machine there is arranged a foot rest B mounted on a fixed shaft B, and around this. shaft is a fixed, metallic bushing B which may, if desired, be cast in one piece with the base plate B Sur- Fig.2 is a plan view of F cast with or secured in anydesired manner to the base plate B At the upper end of this revoluble shaft D there is a fixed pulley D and below the fixed pulley D and above the disk 0 there is a sleeve D around the shaft D, having an extension D provided at its outer end with a sleeve D in which is located the revoluble shaft D which extends upwardly and forms the driving shaft of the brush E secured thereto. a At about the center of the shaft D there is fixed to it the pulley D and around the pulley D and the pulley D there is a driving belt E by which motion from the shaft D is communicated to the shaft D by which the brush E is revolved against the side of the boot as the brush moves around the sides of the boot in a manner hereinafter described.

After the foot has been placed on the rest B and the machine started, as hereinafter described, the brush E moves around the sides of the shoe to cleanthe same, and after this operation the said brush takes its blacking from the blacking pot Gand applies it to the shoe. This blacking pot G has on one side a well G and on the other side a piston chamber inwhich the piston G2 operated by hand moves up and down to supply the brush E with blacking, and in the face of this piston there are out the grooves G to carry the blacking to the brush E, which is then applied to'the shoe, and the continued revolution of the brush E, after the application of the blacking, polishes the shoe. After the sides of the shoe have been polished the foot is raised from the rest B andthe sole of the shoe is placed upon a small rest H in position under the brush J, which is secured to shaft J supported from the top casing of the machine. This brush J appliesblacking to the top of the shoe and polishes the same, and

after the shoe is polished the machine can be thrown out of operation in a man'nerhereinafter described.

The shaft J to which the brush J is socured, is driven by the belt J in a direction indicated by the arrows, and it receives its motion from the same source as the belt 0 which drives the disk 0, as will be hereinafter described. For this top brush J a blacking pot K is provided, and it is of similar construction to the blaoking pot G for the brush E which operates on the sides of the, shoe. It has a well K for the blanking, and piston chamber in which the plunger K moves and which is provided with the grooves K to carry the blacking into the brush J to beap'plied to the top of the shoe. The front of the plunger K where the grooves K are cut is curved to conform to the shape of the brush, as indicated in plan view Fig. 2.

So far I have described the mechanism for blacking the sides and top of the shoe, and without reference to the means for communicating the power to the mechanism for carrying out this purpose, I will now describe the mechanism by which the machine is started in operation.

The motor L is of the usual construction and has an armature L provided on one side with pulley L fixed thereon and beyond said pulley another pulley L also fixed thereon. On the opposite end of the armature there is provided the usual brushes L and thecommutator L When the armature is revolved by the closing of the circuit the pulley L is revolved and drives the belt 0 which revolves' the disk Gin a direction indicated by the arrow, and at the same time the pulley L drives the belt J which revolves the shaft J of the brush J in a direction indicated by the arrows.

provided a chute M in the top casing of the machine of suflicient size to receive a nickel or other suitable coin, which, passing through this chute, enters the pocket M and is held therein,'and by its weight carries down the lever M secured to the weighted sleeve M pivotedto the side of the machine, and which sleeve holds the lever M in the position shown in Fig. 1. In. the downward movement of thislever M and the revolution of the sleeve M on its pivot the pin M secured to the sleeve M strikes the pin M on the key M and raises said key, as shown in Fig. 3, against the tension of the spring M and permits the inward movement of the bar M under the tension of the spring M as shown in Fig. 3. On the bar M near its center, there is provided the pin M which, in the movement of the bar M moves a piece of fiber or insulating material M which is pivotally connected to two metal bars M and by the movement of this bar M under the tension of the spring M after being released from the key M, the two metal bars M are brought into contact with the switch N, by

To close the circuit and thus automatically operate the machine, I have which the electric circuit is closed, and the armature L caused to revolve and with it the pulleys I1, L by which motion is communicated to the disk 0 and the shaft J and the operation of the machine started.

When the circuit has been closed, as above stated, the armature shaft L of the dynamo L and the pulleys U, L mounted on the armature shaft L revolve in a direction indicated by the arrow 0 and move the belts J and C in a direction indicated respectively by the arrows b, c on the said belts. The belt J moving in this direction causes the rotation of the brush J in a direction indicated by the arrow 61. The belt 0 movingin a direction indicated by the arrows c on the said belts" moves the disk 0 in a direction indicated by the arrows e. This direction of movement of the disk G causes the friction pulley D to revolve around the fixed disk F in a direction indicated by the arrow f. This direction of movement of the friction pulley D causes a revolution of the shaft D, which is communicated to the pulley D and moves the belt E in a direction indicated by the arrow g. The brush E is revolved'by the belt E in a direction indicated by the arrow it against the sides of the shoe. This'direction of movement of the belt E and of the brush E, which is driven thereby, tends to hold the brush in close contact with the sides of the shoe in the revolution of the disk 0 and the brush E around the shoe. By this strain of the belt E, moving in the direction indicated, the tendency is to hold the brush E, in its revolution, against the side of the shoe and give an even pressure upon it, in the revolution of the disk 0 in a direction indicated by the arrow 6. The downward movement of the lever M continuesuntilthe projection O on the side 0 of the money pocket M strikes a projection O in the side of the casing and tilts the lower end of the side 0 outwardlyasufiicient distance to permit the coin to drop from the money pocket M into the money receptacle P, after which the lever M returns to its normal position by reason of the weighted sleeve M as previously described.

To break the electric circuit and stop the operation of the machine there is provided the lever Q pivoted in the frame of the ma- :chine and having a projecting handle Q outside of the casing, so that when this lever is operated and the movable bar M to which it is connected, is reversed from the position shown in Fig. Sto that shown in Fig. 1 the key M, under the pressure of the spring M id'rops into a cavity of the bar M at its farthest end and locks said bar M against inward movement and also against the tension iof the spring M and holdsit in this position and breaks the circuit by moving the bars 1M away from the switches N, all as shown in Fig. 1.

I do not limit myself to the exact arrangement and construction shown, as the same may be varied Without departing from the spirit of my invention.
